tvs get their picture and sound on different channels, and in europe, and in the usa the sound is on different channels, try in sound settings to set it to your area's sound defaults, so the tv will search for the sound at the right channels.
If the sound on your DLP TV is out of sync with your picture and the TV is not connected to a home theater system, a Samsung technician can adjust the sound sync function on the TV so that the sound and picture are in sync.
To arrange a service call to adjust the sound sync function, call Samsung Customer Care at 1-800-SAMSUNG (1-800-726-7864).
